More Knowledge About Distribution Substations


A substation is a high-voltage electric system office. It is utilized to switch generators, hardware, and circuits or lines all through a system. It likewise is utilized to change AC voltages starting with one level then onto the next, and/or change alternating current to direct present or direct current to alternating current. A few substations are small with minimal more than a transformer and related switches. Others are expansive with a few transformers and many switches and other hardware. There are three aspects to substations:

Substation Types: Although, there are for the most part four sorts of substations are a combination of two or more sorts.

  • Step up Transmission Substation
  • Step down Transmission Substation
  • Distribution Substation
  • Underground Distribution Substation
  • Substation Functions
  • Substation Equipment

Distribution substations are situated close to the end-users. Distribution substation transformers change the transmission or sub-transmission voltage to lower levels for utilization by end-users. Typical distribution voltages vary from 34,500Y/19,920 volts to 4,160Y/2400 volts.

34,500Y/19,920 volts are interpreted as a three-stage circuit with a grounded neutral source. This would have three high-voltage conductors or wires and one grounded neutral conductor, a sum of four wires. The voltage between the three stage conductors or wires would be 34,500 volts and the voltage between one phase conductor and the neutral ground would be 19,920 volts.

From here the power is distributed to modern, business, and private clients.

Substations are intended to achieve the accompanying functions, although not all substations have every one of these functions:

  • Change voltage starting with one level then onto the next
  • Direct voltage to make up for system voltage changes
  • Switch transmission and distribution circuits into and out of the grid system
  • Measure electric power qualities flowing in the circuits
  • Connect communication signals to the circuits
  • Eliminate lightning and other electrical surges from the system
  • Connect electric generation plants to the system

Electrical Panelboard: Way To Design Them

electrical panelboard

Electrical panel boards serve like the control centre for several electrical systems like, residential wiring. If the electrical panel is well-made, it is simple to access and added electrical systems can be additional to the panel with time. If the panel is ill designed, several problems can rise. The electrical contractor can be employed to design the panel however the cost can be great. Use few expert design methods to make an electrical panelboard, thereby reducing the cost of employing the contractor or designer.


  1. Decide the system’s requirements and individual constituents. In residential arrangements, the electrical requirements of a family alter with time. Room additions might be added to the arrangement for extra family members. Electrical panel board should be designed to house these variations. Prepare a record of the immediate requirements and long term goals. If added electrical components need to be added, the panel should be large enough to lodge those constituents. Record all the constituents that will be measured from the panel.
  1. Have a look at the necessary electrical codes for the project. Even panel’s casing need to be constructed from constituents accepted by the electrical codes. Electrical codes could be assimilated at the State’s Building Standards Commission’s website. Record all the suitable panel material and any statistics referring to the panel’s wiring like breaker loads.
  1. Make a sketch of the panel board. Initiate by drawing the panel’s face outline. Decide a logical order of locations for the panel’s constituents. Panel components, like, switches, must be grouped in clusters as per the use and easy to access. If the panel controls devices on any side of it, the switches for the devices ought to be clustered consequently. Design the panel so that any switches or controls are located in logical locations.

Electric Panel Board: Their Prominent Types

Electric Panel Board

Electric panel board, also known by the name of breaker panel and distribution board is a constituent of an electricity supply system that divides an electrical power feed into its subsidiary circuits, though providing circuit breaker for each circuit or a protective fuse in a common enclosure. Usually, a main switch, and in recent boards, one or more residual current devices (RCD) or residual current breakers with over current protection (RCBO), are also integrated. Depending upon the application, Electric Panel Board is of varied types:

  • Factory Assembled Panel Boards

Factory assembled panel boards are available in all common configurations. They are available directly through distributor stock to help cut down the lead times while providing a dependable solution for the light commercial projects.

  • Lighting Panel Boards

Panel boards are ideal for lighting and appliance branch circuit protection. Products are designed for sequence phase connection that permits complete flexibility of circuit arrangement (1-, 2- or 3-poles) to allow balance of the electrical load on each phase. The types and kinds of lighting panel boards are Fusible Lighting Panel boards, Pow-R-Line 1a and 2a, Pow-R-Line 3a, Pow-R-Line BCM panel board, Pow-R-Line 1R and 2R and Pow-R-Line 3E.

  •  Column Panels

Column Panels offer a proven design for warehouse, commercial and industrial applications. They measure a compact 8-5/8″ wide by 6″ deep and are easily mounted inside an I-beam for industrial applications. The main breaker lugs could be mounted for top or bottom feed. They are ideal for confined areas or renovation projects.

  • Elevator Control Panel board

Control panel boards are designed to meet the stringent requirements commanded by the multiple building codes. These codes are designed to offer fire protection and safety within elevator shafts. The elevator control panel board takes the speculation out of code compliance with respect to the electrical communications and electrical components systems.
